This may be affecting me. Being a backwoods orienteering buff in
the U.S., I use a map datum of NAD27 CONUS. My GPS receiver is set to
work in that datum, also.
I have noticed a greater positional error that should occur when
using my Meade LX200 telescope. (Sometimes by a factor of ten minutes
of arc)
Kevin commented on converting one datum to another. Can someone
tell me the necessary formulas to go from NAD27 CONUS to the two WGS
datums?
And lastly, what datum would we expect automated "go-to" telescopes
would have been engineered with? I am not so sure Meade would
understand what I was asking if I called them.
